quit for no reason

I thought Douglas a great attorney in till June 15th he called wanted to know where some more money was even though my account is paid in full. I found out that I have a mediation on the 17 of June, which he failed to notify me when I asked why he failed to notify me his assistant said that's it they quit.I don't call that very professional do you? I've done nothing wrong but he's dropped the ball left and right yet he is quitting on me even though I'm paid in full.
